I've recently pier mounted my NEQ6 and last night finished my polar alignment so that the star wouldn't move over 10 mins. I've never tried PEC before so decided to give it a go. My results are attached. I captured the data on a DSI II Pro and an Orion short tube 80 (FL 400mm)using PHD. Shot on a star on the meridian near the equator.
I can’t believe that my PE is only +9 -12 arcsecs. I was expecting more like +- 30. What could I have done to get incorrect data that would show a PE less than what it really is? Could it be that the scope that I shot the data through has a focal length that is too short?
I wanted to see how my guiding was going and to my surprise I've never seen it as good as this before. OSC index of 0.19 and RMS of 0.12. I've never seen numbers that good before. Maybe it’s down to a really accurate polar alignment. Any thought here?
Cheers for any help,
